3D Reconstruction of the Human Colon from Capsule Endoscope Video

Abstract

In this paper we investigate the possibility of constructing 3D models of longer sections of the human colon using image sequences obtained from wireless capsule endoscope (WCE) video to provide enhanced viewing for gastroenterologists. As images from WCE contain severe distortions and artifacts non-ideal for 3D reconstruction algorithms, the problem is difficult to attack. However, recent developments of virtual graphics-based models of human gastrointestinal system, where most of the distortions and artifacts can be enabled or disabled, makes it possible to determine how each factor disturbs such algorithms individually. In this paper we disable distortions and artifacts in order to determine if longer sections of the human intestinal environment is at all feasible to reconstruct. Though simulation we show that this is possible using structure from motion and simultaneous localization and mapping (SLAM).
